Evaluation of Antimicrobial & Antioxidant Activities of Methanol Extract of Thysanolaena Maxima.

Abstract

The plant Thysanolaena maxima has been used by the natives in Tao Dam Forest, Bangkok and Khashi traditional healers and village folks in Meghalaya. It is used as a traditional medicine for the treatment of cancer, In case of Red eye and Dirty, in treatment of Dysentery, to facilitate Delivery, in veterinary medicine and as mouth wash in fever. The aim of the present study was to evaluate the antimicrobial activity and antioxidant activity of methanol extract of Thysanolaena maxima. The antimicrobial activities of methanol solvent extract of Thysanolaena maxima plant were tested against the gram-positive and gram-negative bacterial strains by observing the zone of inhibition. The antimicrobial test was performed by disc diffusion method. The crude methanolic extract of Thysanolaena maxima leaves extract showed very low antimicrobial activity against the microorganisms at concentrations of 600 μg/disc. The antioxidant effect of methanolic extract of Thysanolaena maxima was very potent and the power of the extract was increased with quantity of sample. The plant extract could reduce the most Fe3+ ions, which had a lesser reductive activity than the standard of Ascorbic acid. In conclusion, further investigations are needed to identify the active constituents and the exact mechanism(s) of action responsible for the reported antimicrobial and antioxidant properties of Thysanolaena maxima.
